'Thisinvention relates to improvements in retary stands. In cabinetscupboards and the-like it is frequently diificult to reach smallerarticles placed toward the back thereof, and it is therefore an objectof this invention to provide a rotary stand having one or more shelvesthereon which turn with it so that ready access may be had to any of thearticles placed on one of the shelves.

Another object of the invention is to provide a rotary stand which isadjustable as to height so that one of my stands may be installed ineither of several cabinets or cupboards wherein the vertical distancebetween the top and bottom walls differs to some extent.

A further object of the invention is to provide a rotary stand which mayeither be rotatably supported upon the bottom wall of a cabinet orcupboard in which it is installed, or upon a member secured to theunderside of the said bottom wall so that a shelf on the stand isrotatable in an opening formed in the bottom wall and is in horizontalalignment with the latter.

Havin thus briefl stated some of the objects and advantages of theinvention I will now proceed to describe it with the aid of theaccompanying drawing, in which:

Figure 1 is a side elevation showing the rotary stand mounted betweenthe top and bottom walls of a cabinet or cupboard.

Figure 2 is an enlarged view thereof, partly in section.

Figures 3, 4 and 5 are sections on the lines 33, 1-4 and 5-5respectively of Figure 2, and

Figure 6 shows a slightly modification.

Referring to the drawing, l designates a sl in dle having an upperportion 2 of smaller diameter connected to a lower portion 4 of largerdiameter by a downwardly and outwardly tapered collar 3, and the lowerextremity of the H lower portion 4 terminates in a second downwardly andoutwardly tapered collar 5 Extending downwardly from the latter is aprojection 6, or Go. The spindle I is bored at I from its upperextremity for a portion of its length to rnceive a helical spring 8, andmounted also in the bore 1 is a cap 9 the upper end of which is closedand rests on the top of the spring 8. Formed integral with the closedupper end of the cap 9 is a cone ID the lower, larger portion of whichis of somewhat smaller diameter than that of the cap, thereby forming anannular shoulder ll around the top of the latter. Suitably securedaround the outer circumference of the spindle l is an annular retaineri2 having an in- "ternal-fiange 13 around its upper extremity to engagethe shoulder H and limit the upward movement of the cap.

Resting against the underside of the upper wall A of the cabinet orcupboard B is a suitable pad I 4 against the lower face of which a cupI5 is arranged. The underside of the latter is centrally and verticallythreaded for the passage of a screw [6 therethrough which is heldimmovable in the cup by a lock nut ll, Formed in the underside of thescrew is countersink is to receive the upper extremity of the cone Iii.Thus through resilience of the spring 8 and adjustment of the screw IEthe distance between the top of the spindle l and the top. of the cupmay be varied to a marked extent so that the height of my stand may bevaried to suit the distance between the upper and lower walls A and C ofthe cabinet in which the device is to be installed.

Mounted on the tapered collar 3 is an annular supporting member 2|] thebore of which is tapered to correspond with that of the collar.Projecting around the upper portion of the member 20 and integraltherewith is a flange 2! against the underside of which a shelf 22 isheld by a nut 23 in threaded engagement with the outer circumference ofthe lower portion of the said member. A second shelf 2 is provided witha tapered bore 25 to correspond with and engage the tapered periphery ofthe collar 5 on which it rests. Thus both the shelves 22 and TM are sosupported on their respective collars on the spindle I that they rotatewith the latter.

In the arrangement shown in Figures 1 to 5 inclusive the projection 6extending from and beneath the lower collar 5 is of uniform diameterthroughout its length. In this instance a circular opening C is formedthrough the lower wall C to receive the shelf 24, and secured to theunderside of the said lower wall is a plate 2% having an annular recess2'! formed in its upper face. Supported in the recess 2'! by a suit ableretainer 28 is a ball bearing 29 in which the projection 6 is rotatablysupported. Thus the lower shelf 24 is positioned in the same horizontalplane as the lower wall C.

However if it is not desired to cut the said lower wall C I then employthe modified arrangement shown in Figure 6. In that case a flat bearingplate 3!] is suitably secured on the lower wall C and the projection 6aconsists of a pin driven into the underside of the lower flange 5coaxially with the latter; the underside of this pin is downwardlytapered to engage a counter sink 32 formed in the upper face of theplate 30.

While in the foregoing the preferred embodiments of the invention havebeen described and shown it is understood that alterations andmodifications may be made thereto provided the said alterations andmodifications fall within the scope of the appended claim.

What I claim is:

A rotary stand including a thrust bearing adapted to be supported by abottom horizontal wall, a vertical spindle having its lower extremityrotatably mounted in said bearing, a cup adapted to bear against theunderside of a top horizontal wall, the underside of the cup having avertical threaded opening therethrough, a screw extending through saidthreaded opening and projecting beneath the latter, the upper extremityof the spindle being tubular, a cone projecting upwardl from the tubularextremity and supporting the lower extremity of the screw, and a helicalspring in the tubular extremity of the spindle beneath the cone urgingthe latter upwardly and retaining it in contact with the screw as thelatter is rotated to move the cup into engagement with the tophorizontal wall and tending to hold the cup in engagement with saidlatter Wall, and shelves fixed around the spindle intermediately of itsheight for rotation therewith.
